Heck it's perl, so don't even try to understand the code - after all,
perl only barely missed the final round in the last competition for the
next cryptographic algorithm!

That being said, I did some clueless hacking in git-svn.perl and let it
run against the freebsd repo. Now, how's that:

~/src/git/git-svn fetch -r1:10000

git branch -r
  releng/2.0.5
  releng/ALPHA_2_0
  releng/BETA_2_0
  stable/2.0.5
  stable/2.1
  tags/2.0
  tags/2.0.5
  trunk

The revision graph looks OK as well. The git-svn config which I used is:

[svn-remote "svn"]
        url = svn://svn.freebsd.org/base
        fetch = head:refs/remotes/trunk
        branches = releng/*:refs/remotes/releng/*
        branchse = stable/*:refs/remotes/stable/*
        tags = release/*:refs/remotes/tags/*

No typo there, my git svn knows about "branches" and "branchse" now ;)
BTW: In fact there is overlap between releng and stable branches in the
feebsd repo, see 2.0.5.

I'll send a monkey patch in a minute.
